Understanding PFOA and its Health Risks
What is PFOA?
Before we can understand what PFOA is, let’s start at the top of the toxin chain. There is a large group of harmful chemicals called per- and polyfluoroalkyl substances (PFAS). This group has over 9,000 types of chemical compounds with the most common being Perfluorooctane Sulfonate (PFOS), Perfluorooctanoic Acid (PFOA), and Polytetrafluoroethylene (PTFE).
PFAS chemicals are commonly referred to as “Forever Chemicals” today because studies have shown that they accumulate in the human body and are associated with various health issues, including cancer. From this group of forever chemicals, PFOA (also called C8) and PFOS are known for their durability and ability to repel water and oil which is why they have been widely used in many products such as food packaging, personal care items, carpets, firefighting foam, and non-stick cookware.
PFOA in the Manufacturing of Cookware
PFOA was once a key ingredient in the creation of non-stick coatings like Teflon. However, due to health and environmental concerns, the use of PFOA has changed significantly in recent years. In fact, around two decades ago, the United States and Canada phased out PFOA in the manufacturing of cookware due to its potential health risks, including links to cancer and developmental issues.
While trace amounts of PFOA might still be present in older cookware, modern non-stick coatings use alternative, PFOA-free substances. Although this shift was positive for health and safety, it’s important to note that some newer alternatives are still under investigation for potential health impacts. This highlights the ongoing need for research and development in safe and sustainable non-stick solutions.
The Health Concerns Linked to PFOA Exposure
Exposure to PFOA has been linked to several health concerns, raising significant alarms in the medical and environmental communities. Studies have linked PFOA exposure with various health issues, including:
- Increased risk of certain types of cancers, including those affecting the kidneys, testicles, and thyroid
- Lower birth weights and developmental delays
- Immune system impairments
- Disruptions to the endocrine system
- Thyroid disorders and hormonal disruptions
- Impact on cholesterol levels, liver function, and fertility
PFOA’s ability to accumulate and persist both in the environment and in human bodies over long periods of time exacerbates these health risks, making its impact a long-term concern for both individual and public health.
While research continues to unravel the full picture, the growing evidence highlights the importance of limiting exposure to PFOA and explains why many consumers are now seeking non-toxic, PFOA-free cookware alternatives.
Ceramic Cookware Defined
Ceramic cookware encompasses two main types: pure ceramic and ceramic-coated. Pure ceramic cookware is made entirely of clay that has been baked in a kiln and is known for its ability to withstand very high temperatures, making it ideal for a variety of cooking methods.
On the other hand, ceramic-coated cookware typically has a metal core, such as stainless steel or aluminum, with a ceramic coating applied over it. This coating is non-stick and free from harmful chemicals, offering a healthier, PFOA-free cookware alternative to traditional non-stick surfaces.
Benefits of Ceramic
Ceramic cookware offers many advantages;
- Even Heat Distribution: Ensures uniform cooking, minimizing the risk of hot spots.
- Versatility: Suitable for various cooking methods, including stovetop, oven, and sometimes microwave use.
- Non-Stick Surface: Natural non-stick properties allow for easy food release and cleanup, often requiring less oil or butter.
- Chemical-Free Cooking: Free from PFOA and often PTFE, offering a safer cooking surface that doesn’t release toxic fumes.
- Non-Reactive: Ceramic is an inert material which means it does not react with food, thus preserving the food’s nutritional value and flavor integrity.
- Durability: Pure ceramic cookware is extremely durable and resistant to chips and scratches.
- Heat Retention: Excellent at retaining heat and keeping food warm for longer periods.
- Aesthetic Appeal: Available in a variety of colors and styles, adding beauty to kitchen decor.
- Eco-Friendly: Made from natural materials, making it a more environmentally friendly option.
- Easy to Clean: The cookware is typically dishwasher safe, though hand washing is recommended to extend its life.
- Healthier Cooking: The non-toxic surface allows for cooking with less fat and a lower risk of chemical leaching.
Is Ceramic Safe?
Traditional non-stick pans are often criticized for containing PFAS, also known as “forever chemicals,” which include compounds like Perfluorooctanoic acid (PFOA). Because of their persistence in the environment and potential health risks, PFOA was banned in the United States in 2015.
CAUTION: cookware manufactured in countries without the same safety regulations found in the U.S. may not be free of PFOA
Despite PFOA’s phase-out, it can be assumed that all non-stick coatings are made with polytetrafluoroethylene (PTFE), unless it is ceramic. Ceramic coatings differ fundamentally from traditional non-stick technology and typically do not contain PFOA, PTFE, or Teflon.
However, it is important to point out that a label claiming to be “PFOA-free” doesn’t guarantee the absence of all risks. Unfortunately, advertising is often misleading because it emphasizes what’s missing from the product (like PFOA) but neglects to mention the presence of PTFE. Additionally, some of the substitute chemicals that are now used instead of PFOA, like GenX, may pose similar health risks, but there hasn’t been enough time to sufficiently study them.
One concern about ceramic-coated cookware has to do with its metal core and whether the metal can leach into the food. Thanks to the multiple layers of tough ceramic coating, high-quality ceramic-coated cookware effectively prevents any contact between the food and the metal core. As long as the ceramic coating has not been compromised by overheating or damage, the protective ceramic layer can remain effective.
Proposition 65
Starting in 2024, California has a new regulation for cookware makers. They must tell buyers if their products have dangerous chemicals. California already has a rule, called Proposition 65, that lists over 800 harmful chemicals not allowed in cookware, like lead, mercury and cadmium. Products with these chemicals need a warning label. The new law will help buyers know more about what’s in their cookware, making shopping for safe pans easier.
Proper Care
Proper maintenance of ceramic-coated cookware is crucial for preserving its safety and durability. Here are some recommendations to help maintain the integrity of the ceramic coating:
- Avoid Overheating: High temperatures can damage the coating. Some pans are oven-safe so be sure to follow the guidelines recommended by your cookware brand.
- Hand-Washing: Hand-washing can help prevent the abrasive action of dishwasher detergents from wearing down the ceramic coating over time. While many brands have dishwasher safe ceramic products, you may still choose to hand wash.
- Use Proper Utensils: Using the right utensils is also critical for maintaining the ceramic coating of your cookware. Choose wooden or silicone tools instead of metal to prevent scratches.
- Safe Storage: It is advisable to store your ceramic-coated cookware carefully to avoid chips and cracks
Following these guidelines ensures the longevity of your ceramic-coated cookware and keeps your food safe from potential contaminants.
Is Pure Ceramic Free of PFOA?
The natural ceramic layer of pure ceramic cookware is crafted entirely from fired clay so it is, indeed, free of harmful chemicals like PFOA. However, some pure ceramic cookware is glazed to enhance its durability and aesthetics. Some glazes historically contained lead and cadmium, raising concerns about potential leaching into food.
The good news is that modern regulations and responsible manufacturers have significantly reduced the risk. Many reputable brands use glazes certified as food-safe and free of harmful heavy metals. However, it’s still wise to be cautious. Choose cookware from trusted brands known for using safe glazes.
When in doubt, look for certifications like NSF International or FDA approval. Remember, transparency is key. If a brand doesn’t readily disclose the ingredients of their glazes, it’s best to err on the side of caution and choose another option.
